Plant growth-regulating azolyl spiro compounds

Abstract

Plant growth-regulating azolyl spiro compounds of the formula ##STR1## in which R stands for halogen, alkyl, alkoxy, alkylthio, optionally substituted phenyl, optionally substituted phenoxy, amino, alkylamino and/or dialkylamino, n stands for the numbers 0, 1, 2 or 3 and X stands for nitrogen or a CH group, and addition products thereof with acids and metal salts.

What is claimed is: 
     
       1. An azolyl spiro compound of the formula ##STR23## in which R stands for fluorine, chlorine, bromine, iodine, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, alkylthio having 1 to 4 carbon atoms, phenyl which is optionally substituted by halogen or alkyl having 1 to 4 carbon atoms, phenoxy which is optionally substituted by halogen or alkyl having 1 to 4 carbon atoms, amino, alkylamino having 1 to 4 carbon atoms or dialkylamino having 1 to 4 carbon atoms in each alkyl group, and n stands for the numbers 0, 1, 2 or 3, or an addition product thereof with an acid or metal salt.   
     
     
       2. An azolyl spiro compound or addition product according to claim 1, in which R stands for fluorine, chlorine, bromine, iodine, methyl, ethyl, n-propyl, isopropyl, n-butyl, sec.-butyl, iso-butyl, tert.-butyl, methoxy, ethoxy, methylthio, ethylthio, phenyl which is optionally monosubstituted or disubstituted by identical or different substituents from the group consisting of fluorine, chlorine, bromine and methyl, for phenoxy which is optionally monosubstituted or disubstituted by identical or different substituents from the group consisting of fluorine, chlorine, bromine and methyl, for amino, methylamino, ethylamino, dimethylamino or diethylamino, and   n stands for the numbers 0, 1 or 2.   
     
     
       3. A compound according to claim 1, wherein such compound is ##STR24## or an addition product thereof with an acid or metal salt. 
     
     
       4. A compound according to claim 1, wherein such compound is ##STR25## or an addition product thereof with an acid or metal salt. 
     
     
       5. A compound according to claim 1, wherein such compound is ##STR26## or an addition product thereof with an acid or metal salt. 
     
     
       6. A compound according to claim 1, wherein such compound is ##STR27## or an addition product thereof with an acid or metal salt. 
     
     
       7. A compound according to claim 1, wherein such compound is ##STR28## or an addition product thereof with an acid or metal salt. 
     
     
       8. A plant growth-regulating composition comprising a plant growth-regulating effective amount of a compound or addition product according to claim 1 and an inert diluent. 
     
     
       9. A method of regulating the growth of plants which comprises applying to such plants or to a locus in which said plants are growing or are to be grown a plant growth-regulating effective amount of a compound or addition product according to claim 1. 
     
     
       10. The method according to claim 9, wherein such compound is ##STR29## or an addition product thereof with an acid or metal salt.
